CVE-2026-1435
CriticalSummary
W podatności CVE-2026-1435 w interfejsie webowym Graylog w wersji 2.2.3 nieprawidłowo zarządzane jest unieważnianie sesji po nowych logowaniach. Aplikacja generuje nowy 'sessionId' przy każdym logowaniu, ale nie unieważnia wcześniej wydanych identyfikatorów sesji, co pozwala na ich dalsze używanie.
Risk Assessment
Ryzyko dla organizacji polega na tym, że skradziony lub wycieknięty 'sessionId' może być użyty do nieautoryzowanego dostępu do aplikacji, co może prowadzić do kompromitacji konta i interakcji z API/web.
Recommendation
Zaleca się aktualizację do najnowszej wersji Graylog, która poprawia zarządzanie unieważnianiem sesji oraz wdrożenie dodatkowych środków bezpieczeństwa, takich jak monitorowanie i ograniczenie dostępu do sieci API.

Original NVD description (English source)
Not properly invalidated session vulnerability in Graylog Web Interface, version 2.2.3, due to incorrect management of session invalidation after new logins. The application generates a new 'sessionId' each time a user authenticates, but does not invalidate previously issued session identifiers, which remain valid even after multiple consecutive logins by the same user. As a result, a stolen or leaked 'sessionId' can continue to be used to authenticate valid requests. Exploiting this vulnerability would allow an attacker with access to the web service/API network (port 9000 or HTTP/S endpoint of the server) to reuse an old session token to gain unauthorized access to the application, interact with the API/web, and compromise the integrity of the affected account.
